Sandbox Test Tools
Instant Payment Notification Simulator
6
You can modify the fields that you want to include in the IPN; however, the simulator does not
check the validity of any field that you change.
NOTE: By default, only populated fields are displayed. You can check the Show all
fields box to view all fields.
After you have viewed or modified the fields to be sent, click Send IPN. The results of the
operation are displayed at the top of the page.
Testing IPN Messages in the Sandbox
After you use the IPN simulator, you should test actual notifications in the Sandbox as well.
The only difference between a test IPN message and a live IPN message is that PayPal
includes a test_ipn variable in the IPN message. To set up your Sandbox account to handle
IPNs outside of the test tool, click Enter Sandbox Test Site from your test account and
proceed as if you are using a live account. See
Instant Payment Notification Guide for more
information.
